Limited treatment options such as antibodies targeting HER2 and immuno-checkpoint inhibitors are currently available for advanced gastric cancer, whose response rates remain unsatisfactory. Thus, novel anti-cancer agents with different mechanisms are indispensable for improvement of treatment outcomes of patients with GC.<\/p>\n<p>Transmembrane Receptor, cholinergic receptor nicotinic beta 2 subunit (CHRNB2) has been identified via comprehensive transcriptome analysis of 300 resected tissues from stage III GC patients.
